Post-installation notes on the error log

After installation is complete, use the administrative console to change the log stream name or create new log stream names for servers or servants.

Note:
  • A server's error log stream setting overrides the general WebSphere® Application Server for z/OS® setting, and a servant setting overrides a server setting. Thus, you can set up general error logging, but direct error logging for servers or servants to specific log streams.
  • If you create a new log stream name through the administrative console, you must configure a new log stream on z/OS and, if using the coupling facility, define a corresponding new coupling facility log stream.
  • If you changed an existing log stream, or created a new one, you probably need to restart WebSphere Application Server for z/OS. When the name of a log stream is changed through the administrative console, in most cases a restart of WebSphere Application Server for z/OS is required before the change becomes effective. The only case when the change takes effect automatically is when the log stream name is changed for a server along with other changes that cause the server to be restarted.

If you want WebSphere Application Server for z/OS messages that occur during execution of a z/OS client to be recorded in an error log stream, code the client_ras_logstreamname WebSphere variable in its environment file then initialize the client. For more information about client_ras_logstreamname and the related variable ras_log_logstreamName, see the WebSphere variables in the administrative console or the information center.

Our RACF® samples BBOWBRAC and BBODBRAC give UPDATE authority to the runtime control and servant user IDs for the log stream you created (they require that you supply a log stream name). After installation and customization, if you want to grant access to the log stream: Follow the sample RACF commands in BBOWBRAC or BBODBRAC.
